34 Claims.

The present invention relates to sewing machines, preferably but not necessarily of the type wherein the needle is double pointed and has its eye located between the points, and wherein the opposite ends of the needle are grasped alternately by the jaws of opposed needle bars, such type of machine admirably lending itself for adaptation or modification into a machine for sewing together four-in-hand neckties and their linings, for example, whereby it is possible and practical to rapidly make complete neckties known in the trade as "slip stitch neckties.

Other objects of the invention are to provide novel means for feeding the work, novel means for pulling the loose end of the thread through the work at the completion of each stitch, and novel means for more especially adapting the machine for supporting and holding a tie and its lining in position for sewing them together.

These and other objects of the invention being in view, the same consists of certain features of construction and combinations of parts to be hereinafter described and then claimed with reference to the accompanying drawings illustrating a preferred embodiment of the invention and wherein Fig. 1 is a side elevation, partly in section, of a sewing machine according to the present invention:

Fig. 12 is a sectional detail of the preferred means for holding and positioning one end bf the thread;

Fig. 13 is an elevation taken at right angles to Fig. 12;

Figs. 14, 15, 16, 17 and 18 are detail views to graphically illustrate the manner in which the machine operates in sewing the work; and

Fig. 19 is a plan of the tie as sewn to the lining similarly with the same parts as shown in Fig. 7.

Referring more particularly to Figs. 1 and 3, they show a sewing machine comprising the parts ID on a stationary frame, the upright ll extending therefrom and the sewing machine arm l2. As the machine illustrated is of the type referred to, the same is provided with a power shaft l3 mounted in a bearing of the upright II, a belt pulley l 4 on the shaft and a belt H on the pulley, which belt is driven by an electric motor or otherwise, provided with well known means of control. The pulley I4 is provided at its inner face with an enlarged disk portion l6 having at its inner face a profiled cam H which extends annularly around the disk.

Rollers l8, I8 are positioned at diametrically opposite points of the disk l6 to bear on the surface of the cam i1, these rollers being carried at the rearward ends of oscillatory arms I9, 20. Each of the arms I9, 2|) is mounted upon an intermediate pivot stud 2l extending from the upright l I. An upper needle bar 22 and a lower needle bar 23 arranged in alignment are connected by pin-and-slot connections, respectively, with the arms I9 and 20 whereby to convert the oscillatory motion of the arms into a rectilinear motion of the needle bars. Each needle bar is made as more clearly shown in Fig. 11. The needle bars 22 and 23 are guided respectively in a pair of guides 24 and a pair of guides 24a. The guides 24 are formed by lugs on the sewing machine arm I! and the support for the guides or lugs 24a will be specifically described hereinafter. The parts of the needle bar are well known as well as the type of needle carried by such needle bars and such parts will now be described.

A double pointed needle 25 is provided, that is one having a point at each end, between which points is located the eye 26, at about the midlength of the needle. Tapered caps 21 are screwed onto the corresponding ends of the needle bars and the same serve to confine spring pressed shanks 28, said springs being arranged to abut the upper and lower ends of the hollow needle bars, respectively, to exert spring action upon the shanks 28. Positioned on the outer ends of the shanks 28 are caps or heads 22a, and 23a, and

the opposite ends of the shanks 24 are provided with spring laws 29.

It will be understood by those skilled with this type of machine that the needle 25 is alternately grasped by the laws 29 of each needle bar. Brieily the action is such that as the oscillating arm l9 carries the needle bar 22 inwardly toward the work, the nut or head 22a will abut the upper lug or stop 24 with the result that the needle is re leased from the upper needle bar, the needle being taken over by the lower needle bar in the same way that the upper needle bar does the some. The upper needle bar in taking the needle from the lower needle bar is caused to rise and to remove the head 224: from engagement with the stop 24, so that at the moment this occurs the Jaws 29 are caused to clutch the needle by reason of the spring in the needle bar 22 being free to act to force the jaws into the tapered cap 21. In other words, whenever the head 22a. is out of engagement with the stop 24, the spring in the needle bar 22 is free to press the gripping jaws 29 into the tapering cap 21, thereby causing such jaws to grip the needle. The spring of the lower needle bar acts alternately therewith in the same manner.

A presser foot lll is provided which is operated by a lever 9| on the machine arm 12 which in turn is operated through the medium of a roller 32 located on the lever Ii, which roller rides over cam projections 35, 44 carried by a part of the machine to be hereinafter described. A stationary plate 35 as shown in detail in Fig. 10 is mounted on the upper end of a support 35 mounted on a part hereinafter described. This plate 35 is disposed horizontally in a plane parallel with the plane of feed of the work and is provided with a slot 51 forming a throat through which the needle 25 may be caused to pass during the sewing operation. Plate 55 is furthermore provided with a guide rib 58 in which the throat I1 is directly located. Such rib Ill extends in the direction of the feed.

A stationary table top 49 is provided, the same having mounted thereupon a pair of guide-rails 44 and a separate pair of guide-rails 4|, there being a pair of rails at each side of the line along which the stitching is performed by the machine. These guide-rails 49, 4| are parallel and are adapted to guide a traveling material supporting platform 42, through the medium of anti-friction rollers 42 at each side edge of the traveling platform. Said platform 42 is provided as more clearly shown in Figs. 3, 6 and 9 with a longitudinal slot 44 which receives the longitudinal rib 98 of the throat plate 55. The platform is centered against lateral movement by being confined between guide rails 49, 4| and is permitted to travel longitudinally when operated by the work feeding mechanism. The rib It provides a stationary support for the work immediately around the needle, the upper surface of which is preferably on a level with the top surface of the platform 42, so that the work will not be gathered or drawn when the needle passes through the same.

There is a profiled recess 45 in the platform 42, such recess being bisected by the longitudinal slot 44. This recess is preferably profiled to accord with the shape of the piece of lining which is to be used in sewing it onto neckties 45 of the fourin-hand type, as shown in Fig. 7. The lining 41 is placed in the recess 45, and having been properly positioned longitudinally with the direction of feed, the longitudinal edge portions of the folded tie 45 are placed over onto the lining,

there being preferably an intervening tape 48 be tween the tie and the lining, as shown in Fig. 7. Further explanations in these connections will be made later on.

Referring to Figs. 1, 3 and 4 there is mounted rigidly upon the power shaft l3 a large gearwheel 49 for the purpose hereinafter described. This gear-wheel is provided with an enlarged disk portion 59 on which the cams 93, 34 are located, which cams are for the pu p se of operating the presser foot 99. The disk portion is provided in its forward face with a cam or eccentric groove 5| which controls the operation of the feeding mechanism. The feeding mechanism comprises an oscillatory lever 52 having a pin 59 positioned in the cam groove 5|, such lever being mounted upon a. bracket 54 by means of a. pivot 55 so located as to provide two arms to said lever, one of which carries the said cam pin 53. The bracket 54 is fixed to the lower one of the stationary guide rails 4|. The lower arm of the lever 52 is operatively connected with a link 51 by means of a pivot 59 at one end of said link. The upper arm of lever 52 is connected with a link 59 by means of a pivot 59.

By means of the lever 52 the links or arms 51, 59 are caused to reciprocate alternately in opposite directions for the purpose of operating the pawls of the pawl and ratchet mechanism more clearly shown in Figs. 1, 4 and 5. This mechanism comprises pawl carriers 5 I 62 to which the adjacent ends of the arms or links 51, 59 are pivoted. To this end the pawl carriers BI, 62 are made of U-shape as in Fig. 3 and the ends of the links 51, 59 project into the recesses formed by the shape of said pawl carriers. These pawl carriers BI, 52 straddle a. short guide bar 59 which is fixed to the lower bar of the guide rails 4|. The pawl carriers are so mounted upon the guide bar 53 as to be freely movable thereupon when operated by the links 51, 59. One of the carriers 5|, 52 is provided with a pawl 54 and the other carrier with a pawl 55. These pawls are in the shape of short stems, corresponding ends of which are beveled in the same direction, and the beveled or toothed ends thereof are pushed outwardly through the intervention of helical springs 66 coiled within the carriers GI, 52. The action of the springs 56 is to cause the beveled or toothed ends of the pawls to engage or take between the ratchet teeth of a rackbar 51. This rack-bar 61 is fixed to the underside of the intermittently movable traveling platform 42 which supports the work.

It will be seen that the action of the cam 5| on the oscillating lever 52 is such as to alternately reciprocate the links 51, 59 in opposite directions and that the traveling platform 42 is moved to advance the work at each operative engagement of the pawls 64, 55. The arrangement and operation of the involved parts in this connection are such that as the pawl 54 moves forwardly in operative engagement with the ratchet teeth of rack 61, the pawl 55 is moved in opposite direction so as to idle over the ratchet teeth. When the pawl 65 is moving in reverse direction it is in operative engagement with the teeth of the rack so as to feed the platform, while the other pawl 64 idles in reverse direction. Thus the traveling platform is caused to advance at the end of each stitch formed in the work. Suitable release means for the pawls may be provided whereby to disengage their toothed ends from the rack bar 51, whereby to permit the traveling platform to be moved back to normal position after the completion of the sewing of each piece of work and to begin upon another piece of work. Such means may comprise a pull chain 68 or the like which is operated in any suitable way.

Now referring to Figs. 3. 6, 'l, 8 and 9, the means for engaging and holding the work will be described. An elongated gage bar 69 is provided which is arranged and mounted so as to extend longitudinally with the direction of feed. This gage bar 69 is provided with a material engaging flange Ill (Fig. 9) which is provided with prongs or sharp teeth ll. Hinges I2 are connected with the innermost edge of gage bar 69, such hinges being fixed to the inner edge portion of the traveling platform 42 as shown in Fig. 3. By swinging the gage bar down upon its hinges, its prongs II will be caused to penetrate the neck-tie lining 41 and the tape 48 thereover, thereby positively retaining them in position in the recess 45. When the gage bar is so positioned, its flange 10 constitutes the gage proper for the edges of the tie which are to be sewed together. Transverse slots 13 are formed in the gage bar 69 and through these pass set-screws 14 which are adapted to screw into the adjacent leaves of the hinges 12, thereby to render the gage bar laterally adjustable so as to determine the distance of the meeting edges of the tie from the line of stitching which is to be formed.

Referring to Figs. 1, 3 and 9, the mechanism for engaging the loops as formed from the thread in stitching and the drawing or pulling out of the free end portion of the thread, will now be described. A gear wheel 15 meshing with the larger gear 49 heretofore referred to rotates at greater speed with a counter-shaft 15 mounted in suitable bearings on a bracket 11 and of a circular stationary support 18, these parts being mounted on the frame of the machine at points below the horizontal plane of the platform 42. This circular stationary member or support 18 is made of large diameter for reasons as will appear herefrom.

A slot 19 extending radially is formed in the circular stationary member 18, such slot extending vertically and receiving within it the lower needle bar 23. The guide lugs 24a of said needle bar and which were before mentioned are fixed to one of the vertlca1 walls of the slot 19 so as to guide the needle bar 23 vertically. A train of gears 80, BI and 82 is mounted upon the front face of the circular stationary member 18, which is formed with a recess 83 to receive the same. The gear is mounted on the shaft 16 and the gear 92 is an intermediate gear between gear 90 and gear Bl which is in the form of a toothed annulus or ring mounted so that it may be rotated upon a circular track disk 84 which is rigidly fixed by means of screws 85 to the front face of the circular stationary member 18. A detail of this construction is shown in Fig. 2. showing also ball bearings, 86, for the rotary element. It will be seen that the axis of rotation of the gear annulus or ring BI is eccentric to the axis of the large stationary member 18.

The thread puller 81 having a forward pointed end is mounted so that it may be carried in a circular path around the periphery of the circular stationary member 18. The thread puller is fixed on the outer end of a carrier arm 88 which is pivoted on a pivot 89 fixed at the axis of the stationary circular member 18. For operating the arm 88 and the thread puller 81, a button or block 90 is mounted so that it is slidable in a longitudinal slot 9| of said arm, said block being swiveled upon a pivot stud 94a. extending from the front side of the toothed annulus or ring 9|. It will be seen that the turning of the toothed annulus Bl will thereby be enabled to move the thread puller 81 in its circular path by acting to rotate the arm 98 around its pivot 89.

By the inclusion of a slidable connection between the annulus or gear BI and the arm 88, the thread puller 87 is caused to move more slowly when it is about to pull or is first pulling the thread out from the work than when it is moving away from the work in entirely pulling out the thread. Therefore the fact is that the thread puller does not act with such quickness in starting the pull of the thread from the work with a tendency to fray out the thread after a number of pulls or with a. tendency to jerk and break the thread, but after the pull is started. the thread puller pulls faster when the danger is over. Specifically the action of the illustrated thread puller is to pull with gradually increasing speed from about the time that it first engages with the thread, and then the puller is returned toward its thread pulling position at a gradually decreasing speed.

Referring to Figs. 6, 12 and 13, a notched thread securer 92 is shown which is mounted fixedly on the left hand or advancing end of the traveling work supporting platform 42. Preferably the thread used in sewing is cut into suitable lengths and one end of each length is knotted and the knotted end engaged in the notch of the thread securer 92 as shown in Fig. 12.

The operation of the machine will now be described briefly, more particularly in connection with the sewing of linings to neckties. The prodnot of the machine is shown in Fig. 19 where it will be seen that the edges of the folded over tie are connected by a line of stitching which extends through the lining 41 and the intervening tape 48 which is preferably employed. The machine produces a sewn tie which as shown is wrong-side out, but which has to be turned or reversed so as to bring the lining and tape into the tie and form a finished tie constructed the same as a hand made tie. When the thread is secured at one end by the thread securer 92, it is threaded through the eye of the needle 25, said needle being held by the upper needle bar. The lining, tape and tie are then placed in their proper positions upon the traveling platform 42, with the edges of the folded over tie in contact with the flange of the gage bar 69, the platform 42 being over to the right to its starting position. The machine may now be started and the traveling platform 42 carries the work to the left during the stitching, the operator taking care that the tie is properly held up to the gage bar. The feed of the traveling platform 42 will be intermittent during the stitching, the said feed being controlled by the cam 5| which through the mechanism previously described alternately operates the feed pawls B4, 65 and these engage the teeth of the rack-bar B1 of the traveling platform.

The needle 25 is passed through the work aiternately in opposite directions, thereby carrying the thread with it, the needle bars acting in well known manner to successively engage and release the needle. The successive steps in the process of sewing are illustrated in Figs. 14 to.18 inclusive, which may be considered in connection with Fig. 9, these views also illustrating the method of forming regular or similarly sized loops from the free end portion of the thread at points below the work as the work'advances. In Fig. 14 the needle is shown as having passed through the work through the action of the upper needle bar and as having been grasped by the jaws of the lower needle bar 23. The thread T being held at one end at a point away from the needle, it is drawn through the fabric in the form of a loop L to receive the pointed end of the thread puller 81 as it is moved around by the mechanism previously described. In the extreme outward position the loop will present the appearance shown in broken lines in Fig. 9, but just as soon as the needle bar 23 moves upwardly for a short distance, the loop will be loosened into the full line position, shown in said figure, at which time the thread puller 81 enters the loop L and as the thread puller is moving continuously it will promptly act to pull the free portion of the thread out from the fabric as shown in Fig. 15. This loose portion is carried by the thread puller upon the periphery of the circular stationary member 18 as the puller moves rearwardly in its own circle of movement. The upwardly reciprocating needle bar 23 causes the needle to pass through the work for the length of the stitch S, the needle then being grasped by the jaws of the upper needle bar 22, carrying the thread with it and forming a loop L as shown in Fig. 16. The work is now advanced for the length of a second stitch S as the needle is moved down through the work, such needle being grasped by the jaws of the lower needle bar 23 upon release from the upper needle bar, so that the thread is laid into the position substantially as shown in Fig. 17. From Fig. 17 it will be seen that a loop L corresponding substantially in size with the previous loop L formed below the traveling platform has been formed along the work and that the free portion of the thread extends through it for the length of such stitch S At about this time the thread puller 81 comes into action and engages the loop L so as to pull out the free portion of the thread from the two points of the work through which it passes, thereby producing the result shown in Fig. 18 where the remaining portion of the thread is seen to be entirely free from the work and may hang as a loose end. As the stitching advances the formation of successive similarly sized loops and the sewing of the work are completed and the machine is stopped and the work, consisting in this instance of the stitched tie and lining, is removed from the machine. of course the presser foot 30 engages with the work each time the needle is passed through it, but is released therefrom for a moment, at the time when the work is being fed forward intermittently.

Obviously the invention is susceptible to a more or less wide range of modification which can be resorted to by those skilled in the art without departing from the spirit of the invention as defined in the scope of the appended claims.
